MAX8831EVKIT：Evaluation Kit for the MAX8831

The MAX8831 evaluation kit (EV kit) is a fully assembled and tested PCB for evaluating the MAX8831 white LED step-up converter. The MAX8831 EV kit operates from an input supply range of 2.7V to 5.5V and is controlled by an I²C interface. The MAX8831 features a 60mA, 28V PWM DC-DC step-up converter with five low-dropout LED current regulators. Each of the five current regulators accommodates up to 9 series LEDs (depending on LED string forward voltage), and are independently programmed using an I²C interface. The I²C interface controls all operational aspects of the current regulators, including on/off state, LED current, ramp-up/ramp-down timers, and blink rate timers (LED3, LED4, and LED5). The MAX8831 EV kit also includes Windows® 2000/XP- and Windows Vista®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the MAX8831. The MAX8831 EV kit features an I²C interface to control the LED current, ramp-up/ramp-down time, and blink on/off time. To control the MAX8831 EV kit from a PC, order the CMAXQUSB command module along with the MAX8831 EV kit.
